Adding support for `cat a.out | size -`

Yes, I think that this will be OK.  Although to be helpful to distribution
packagers it would be nice if there was a configure time option that could
disable this new behaviour.  That way, if too many users complain to a 
distribution maintainer they can choose to turn the feature off.  (But
honestly I doubt if anyone will complain.  Having a file named "-" is going
problems with lots of other tools, not just the binutils).

Cheers
